Cross-Layer Throughput Analysis for Optical Code Labelled GMPLS Networks Conference Paper uri icon

abstract

  • The use of Optical CDMA as a labelling mechanism in Generalized Multi-Protocol Label Switching (GMPLS) optical networks significantly increases the traffic isolation capabilities. These networks, referred to as Optical Code labelled GMPLS (OC-GMPLS), have higher resource utilization due to the finer flow granularity introduced into the network. In this paper we present a cross-layer mathematical model for the throughput of OC-GMPLS networks, which provides a quantitative measure for the performance of optical networks throughput taking into consideration the effect of the physical layer. The proposed mathematical model incorporates the physical layer effects on the network layer performance by expressing the throughput as a function of the physical layer bit error rate, as well as the network traffic parameters such as the number of users and the packet length. Using the developed analytical model we were able to demonstrate the significant enhancement in the network performance due to the use of OC-GMPLS. We also used our analytical model to derive several optimum network operating points, which are of great importance to network designers and researchers. 2005 IEEE.
